We're dividing 285159 by 61 
The aim is to understand the frequency of 61 in 285159.

Going ahead to step 1:
When dividing 2 by 61, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 61

Advancing to step 2:
When dividing 28 by 61, we get 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 61

Step 3:
The number 61 fits into 285 4 times, leaving a remainder of 41.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 41 after subtracting 244 from 285.
Append the next digit (1) from the dividend to 41 and continue with: 411 / 61

Step 4:
61 can be fit into 411 6 times, resulting in a remainder of 45.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we take 366 away from 411, we end up with 45.
Bring next digit (5) of the dividend behind the 45 and repeat the process: 455 / 61

Advancing to step 5:
The number 61 fits into 455 7 times, leaving a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 467.0
Subtract 427 from 455 to get 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 61

Advancing to step 6:
289 divided by 61 is 4 with a remainder of 45.
Use 4 as the next digit of our solution. 
Result so far: 4674.0
If we take 244 away from 289, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
If we divide 450 by 61, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 4674.7
Subtract 427 from 450 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 8:
230 divided by 61 is 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 4674.73
If we take 183 away from 230, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
470 divided by 61 is 7 with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 4674.737
If we subtract 427 from 470, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 10:
430 divided by 61 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 4674.7377
Subtract 427 from 430 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 4674.7377 and a remainder of 3e-05.
